Muta began life with two concerts in Norway in September 2003, though previously the musicians have played together in various combinations since 2000. The three piece group works with specific aspects of sound and dynamics - pitch, silence, noise and drones - all mixed in an improvising environment. Each member works with extended techniques on their instruments with the aim of producing a group sound. The word muta has different meanings; moult, change, development, change of skin, change of hair. The band Muta searches for changes and variation in musical structures and slow/minimal developments of specific sounds and/or pitches.
